sprin s It spring 20 is arranged between seats 13 and l8. At an intermediate portion in its length the load-carrying nieinher is provided with laterally separated portions l7 l7 carrying laterallypresented bosses, iii, 21 which are tronsverscly bored to receive the pivot bolt 22 which in the Ford can provided to form the pivotal connection between the shackle pin 12 and the shackle 23. The side bars 1T"\ 11'' are laterally separated enough to permit the upper end of the shackle pin 12 to {it snugly between the arms, the bolt 22 poseing through the bosses 2i and the shnckle pin. At a point between bosses 21 end spring seats 19 the loml-onriying member i? has a transverse dimension equal to the Width of the shackle pin eye and is trans versely horerl so thz t the regular shackle 22-3 may be coupled to the lOZMl-Cffi'ljflllg momher 17 by means of e bolt or pin 25. The orrangeineiit einl nro portion oil ports is such that in order to 2.1-; 'h my zrievice to the front axle of at Ford corn it is first llGTE/SSZU' Y to disconnect thankles 5 'l'i-oin shoe-kl i pins [53.

the steer-in wheels to swim in 'uhines whi ch are not parallel with the ground and under such circumstances there would be a tendency, after the steering wheels have been turned to one side or another, to suddenly he further deflected in the same direction by the applied load of the vehicle, thus rendering it very diflicult, and even dangerous, to steer the car. By the arrangement shown, it is possible to provide two or the springs 16, upon which the load normally rests, and all of the springs may be considerably longer than would be possible in the precise form of apparatus shown in the Martz patent, and, therefore, a more etlicient absorber is obtained Without the possibility oi? displacing the axes of the steering knuckles from their proper vertical positions. The structure also is more securely held in place and is held in place by the single fastening means of the shackle pin.

In order to obtain the same advantages in the absorbers for the rear axle and in order to make them readily attachable to Ford cars, I have provided the form shown in Figs. l and 5. Here the saddle member is provided at one end with a yoke 3i which straddles and rests upon the tubular portion of the rear axle 32. Extending outwardly from the yoke 31 are parallel 30 which are connected at their ends by a cross plate 33 adapted to lie against the brake band head 34;. This plate'38 is perforated to receive a fastening bolt 35 which receives the nut regularly provided in the Ford car for holding the rear shackle lingers in place.

Extending upwardly from plate is an arm 36 which is'provided with a u Z-l'i having a perforation parallel with the axis of the car, i. e., at right angles to the axis of the rear axle. At its upper end the arm 36 is provided with an inwardlyextended finger 38 which forms a seat for the spring 39. The load-carrying member ll) of this form of the shock absorber is provided at its outer end with a pair of parall l arms 45! which straddle eye 37 and are eorrespoinlingly perforatedso as to receive the hinge bolt 42. At its opposite end the load-carrying member 4:0 is provided with a pair oi parallel arms 43, each of which is provided at outer end with a spring seat 44;. Each side of the yoke 31, at the inner ends of the arms 30, there is a spring seat and between each spring seat and the corresponding spa-inn; seat 44: is a spring 47. At an intermediaie point in its length, the load-carryingmember 40 is provided with :1, trans use perforation adapted to receive a hinge pin 48, by means of which the regular shackle 42:9 oi spring 50 may be attached to the load-carrying member. Upon its upper side, the load-carrying member 41 is provided with a spring seat 51 which receives the lower end of spring 39. The parts are so proportioned that the upper end of the shackle 4-9 occupies the same relative position to spring 50 and the. rear axle 32 that it would it the regular shackle ringer commonly foun d on the Ford car were secured in place by bolt sion thereby. These springs, however, have an initial compression which is coiniter-lnilanced by an initial. compression of the spring 20 and, in order that these oppositely acting springs may deadbeat each other, it is desirable that the period of vibration of springs 16 be diil'erent from the period of vibration oi? spring 20. The same is true 01'? the "form shown in Fig. l, springs 4? assisting in carrv ing the normal load of the vehicle, while spring 39 is arranged in opposition to these springs.
